Facebook sparked a fierce backlash three weeks ago when it began enforcing a "real name" policy against performers and members of the LGBT community. The company initially dug in its heels, refusing to stop requiring people to use their legal names, inciting hundreds of thousands of people to flee to the quasi-anti-corporate network Ello. Now Facebook is feeling the heat and is slated to apologize for the situation later today, sources tell Valleywag.
